Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already mark this read-only, and the description adds pagination behavior via before/after cursors plus the concrete GET endpoint. This is useful beyond the schema, though it does not describe default limits or response shape.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences front-load the purpose, then give pagination and endpoint context with no filler. Every sentence contributes.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only list tool with no required parameters, the purpose, pagination, and endpoint are covered. It could mention the return format or default limit, but nothing essential is missing for selecting and invoking it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter is already documented. The description's mention of before/after cursors for pagination reinforces, but does not substantially add to, the schema definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: lists the metrics configured on a status page. This clearly separates it from sibling listing tools such as statuspal_list_incidents and statuspal_list_services, and the endpoint reinforces the target resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'List the metrics configured on a status page' gives clear context for when to call this tool (need metrics for a status page). It does not name alternatives or state when not to use it, but no prerequisites or competing conditions are left unexplained.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
